Could you advice how to configure/set the values of register with my applications?

Also how to calculate "Loop Filter" or show the suitable values?

For Video, one of two belows selectable to output(single channel LVCMOS):

1. 74.25 MHz (Default)

2. 74.17582418 (74.25/1.001) MHz

For Audio, one of four belows selectable to output(single channel LVCMOS):

1. 8.192 MHz (Defaullt)

2. 11.2896 MHz

3. 12.288 MHz

4. 24.576 MHz

PRIREF = 27MHz OSC

No-SSC, No-DCO

I2C communication

Thanks in advance.

Kamada-san,

TICS Pro can be used to create the register settings.

You can use these buttons to use the default loop filter parameters for fractional or integer PLL configuration. PLL is in fractional mode if "Num" field is > 0.

In the outputs tab, you can calculate the frequency plans. For entering 74.17582418 MHz you can enter 74.25/1.001 as well.

then you will need to click on Calculate Frequency Plan. This will populate the table on the bottom right. Here you need to select one VCO solution and click on apply selected.

Regards,

Julian
